Therefore, in modern communications and microwave system, multiplexer has become very important passive device, and is widely used in frequency modulation radio station, antenna path combining technique and the military field such as anti-interference.
At present, along with the development of the communication technology, multiplexer develops into adjacent type multiplexer by non-neighboring direct type or odd even type multiplexer, and index request is also more and more higher, and the insertion loss constantly requiring channel filtering device is lower, adjacency channel less, the more compact structure of interference; Adjacent type multiplexer is the seamless coverage to communications frequency range, and having very high selectivity is that it can reduce the interference between adjacency channel and multipath effect. Therefore, usually pay the utmost attention to the following two problems of solution when designing this type of multiplexer: highly selective a) meeting multiplexer; B) ensure that structure is simple and loss is low. But there is following defect in various degree in existing multiplexer:
1, asterism formula multiplexer: more multi objective is more poor for number of active lanes, and channel is relatively big to the electrical length closing terminal, affects performance;
2, the many works of directional couple: each channel needs two identical wave filters and two mixed structures, and the line length between wave filter and mixed structure needs accurate balance to keep directivity, and volume and weight is maximum, and final stage Insertion Loss is big;
3, circulator coupling multiplexer: signal continuously through circulator, must introduce extra loss, and low-loss high-power ferrite circulator is expensive, simultaneously with more high performance passive intermodulation product;
4, directional filtering multiplexer: the full limit function that Bart irrigates this and Chebyshev is restricted, opposite band is wider than 10% and is difficult to realize, and the use of single mode wave filter is restricted;
5, branched road coupling multiplexer: design is complicated, and change of frequency adjustable is poor.
